stock tune definetely......mine was tuned after the blower went on....so obviously there was a bit of a change

 

with torque managment you have no throttle responce, Thats the next thing to disable with a tune. an unbelievable difference in throttle responce and power...Shifts when you want it to and in a hurry. HP tuners does a real good job!

 

You have VVT correct, is there a way around it?

 

Why would I want to get around VVT??? Or did you mean AFM?

 

yes im sorry i meant the AFM... but now that i read through the posts i realized it actually is VVT

 

You can turn off AFM and you can set the VVT to not alter the timing so yes you can get around it if you choose.

 

what does VVT actually do?

 

it phazes the cam relative to the crank as rpm changes.

 

On these engines it changes the phasing (timing) of the exhaust valves to improve torque and fuel efficiency. I have no idea what the measured differences are with and without the VVT active.

 

but with one cam controlling both intake and exhaust, it has to phase/vary them at the same doesn't it?
